Dear sefians,

There are 3 stages of Lateral Earth Pressure,

1)At rest
2)Active Earth pressure
3)Passive Earth pressure.
The earth pressure coefficient is different for all the above three cases.

for example, consider a retain wall which is having the soil on one side. When the soil exerts the pressure on wall, it try to move away from the wall. this pressure is known as Active earth pressure.

Likewise, under what condition the passive earth pressure will occur?

As given in text books, the passive earth pressure will occur when the wall moves towards the soil. but how the wall moves towards the soil without any pressrue acting on it? Please explain

Regards,
lakshmi
